Java -如何在Arangodb上创建边？

import com.arangodb.ArangoDB;
import com.arangodb.ArangoDatabase;

public class Main {
    public static void main(String[] args) {
        // 创建ArangoDB实例并连接到服务器
        ArangoDB arangoDB = new ArangoDB.Builder()
                .host("localhost", 8529)
                .user("username")
                .password("password")
                .build();

        // 连接到指定的数据库
        ArangoDatabase db = arangoDB.db("mydb");
    }
}

import com.arangodb.entity.GraphEntity;
import com.arangodb.entity.GraphEntity.GraphEntityBuilder;
import com.arangodb.entity.EdgeDefinitionEntity;

// 创建图的定义
GraphEntityBuilder graphEntityBuilder = new GraphEntityBuilder()
        .name("mygraph")
        .edgeDefinitions(new EdgeDefinitionEntity("myedgecol", Arrays.asList("myvertexcol1", "myvertexcol2")));

// 创建图
GraphEntity graphEntity = db.createGraph(graphEntityBuilder.build());

import com.arangodb.entity.BaseEdgeDocument;

// 创建边的实例
BaseEdgeDocument edge = new BaseEdgeDocument();
edge.setFrom("myvertexcol1/myvertexid1");    // 设置起始节点的ID
edge.setTo("myvertexcol2/myvertexid2");      // 设置目标节点的ID

// 在指定的边集合中插入边
db.graph("mygraph").edgeCollection("myedgecol").insertEdge(edge);
